Often referred to as the World's Toughest Polymer, Ultra High Molecular Weight (UHMW) Polyethylene is your best material choice for making jigs and fixtures for your table saw, router table, drill press, etc. UHMW is a linear high density polyethylene that's 10x heavier than regular high-density polyethylene giving you a rock-solid base for your jig or fixture. UHMW has a low coefficient of friction and is self-lubricating, making it glide over your work surface with little resistance. Plus, this rugged polymer will last for years, as it is highly resistant to abrasions, chemical-resistant, and maintains its high-impact strength even at low temperatures. Choose 24" long stock in 3/4" or 3/8" thicknesses, or a 48" length in 3/8" thickness. All pieces are 4" wide.
